Well ... sorry to hear that ...
I've used Medved Trader for years and have no (spelled 0) interest in using anything else. I am also running Windows 7 on my computer, and have no interest in upgrading that -- if it's not broken, there's nothing to fix; and if I don't leave it alone, I might break it.
As I have MT set up, MT updates are installed automatically and the only way I can tell that is by checking the current version's serial number.
That said, I don't know what caused my "recent problem" with MT; but whatever it was, all my windows (historical and intraday charts and options windows) suddenly had semi-transparent borders (which really annoyed me since the screensaver background image showed through every MT window border). Very annoying! I really wanted solid borders but I couldn't figure out how to do that. So I called MT but they seemed to have little interest in helping me, so they left me dangling (not a great business strategy!).
So I complained to a friend of mine as he might know what I am doing wrong in terms of border selection. He might be able to fix my display problem because when he has a problem with anything he spares no expense to solve that problem. So he invited himself up for a visit (I live way out in the country about an hour away) and he brought along a book that is about four inches thick. He knew nothing about Medved Trader, but he took a half-minute look in his book then sat down at the computer and it only took him about another 30-seconds to fix the problem. Before my friend came up I spent a few hours on it and got nowhere.
All that behind me now, I still wonder how MT managed to change border transparency without my assistance.
